Sunroom Construction Built for Houston Sun
A sunroom in Houston is a glass room facing a sun that does not take summers off, so the glass and the cooling get decided before the framing does. We build new sunrooms as real additions, on a real foundation, tied into your roof and planned so you can sit in it in August.

A new sunroom is an addition to the house, and the city or county treats it that way: drawings, a permit and inspections. It starts at the ground. Greater Houston sits on expansive clay that swells after a week of rain and shrinks in a dry spell, so the new slab or pier-and-beam floor has to be designed for that movement and connected to the existing foundation the way the plan calls for. Floor height matters too. The room should sit high enough that a heavy rain runs away from it, and close enough to the house floor that nobody steps down into a room meant for every day.
The roof decides how the room feels. A solid, insulated roof tied into the existing roofline with proper flashing keeps the midday sun off your head, and it is what we recommend for almost every sunroom in this climate. A full glass roof builds a greenhouse. On the walls, insulated low-E glass with a low solar heat gain rating does most of the work, and the direction the room faces sets the priorities: west and south glass takes the worst of the afternoon, so those walls get the best glass, a deeper overhang, or a little less glass than the brochure shows.
Cooling is the other half. Most central systems were sized for the house as it stood, and hanging a glass room off the end of the ductwork usually leaves the room hot and the system running overtime. A ductless mini-split on its own thermostat is the common answer, and we plan its location, line set and condensate drain before the walls close. Fans rated for the space, outlets on every wall and blinds you can actually reach finish a room that gets used from June to September instead of avoided.
Plenty of Houston sunrooms end up as storage because they cook in summer. Getting the glass, the insulation, the cooling and the roof connection right is what makes the room usable most of the year.
If what you really want is shade and a place for the grill, a patio cover gets you there for less money and with no glass to cool.
When sunroom construction makes sense
The honest version, including the cases where you should spend the money somewhere else.
- You want a new conditioned room off the back of the house, and the yard has the space and the drainage for it.
- Your HOA allows an addition on that side of the house, and you are willing to wait on approval before ground breaks.
- You plan to use the room year round, which means insulated walls, a solid roof and its own cooling instead of a screened summer space.
And when it does not
- If you already have a sunroom that is simply tired, building new is the wrong job, and a renovation of the one you own makes more sense.
- If the only open spot faces due west with no room for an overhang, we will tell you plainly that the room will fight the sun, and show you a smaller or better-shaded option.
How we run it
- I
Site and plan
We look at the yard, the slope, the roofline and which way the room will face, then sketch the room with the glass and cooling choices written in.
- II
Permit and HOA
Drawings go to the city or county permit office, and the HOA package goes in with the product details so approval is in hand before we dig.
- III
Foundation and frame
Forms, steel and concrete or piers come first, then the walls and roof framing, tied into the house with flashing that sheds water the right way.
- IV
Glass, cooling, finish
Windows, insulation, the mini-split, electrical and interior finish go in, followed by final inspection and a walk through the finished room with you.
What we ask before we price it
- What do you want to do in the room?
- How will it be cooled: tied into the house or its own unit?
- Is the existing roof over that area in good shape?
- Is there a slab already, or does one need to be poured?
- Do you want it to match the house outside, or stand apart?
Do I need a permit to build a sunroom?
Yes. A sunroom is an addition, so it needs a permit from your city, or from the county if you live in an unincorporated area. Expect plan review and inspections at the foundation, framing and final stages, and expect the room to meet the energy code like the rest of the house.
Glass roof or solid roof?
In Greater Houston, a solid insulated roof almost every time. A glass roof lets the summer sun straight in from above, and no air conditioner catches up with that by mid-afternoon. Skylights or a row of high windows can bring light in without turning the room into a greenhouse.
Can my existing air conditioner cool the new room?
Sometimes, but rarely well. Most systems were sized for the house without the addition. A ductless mini-split with its own controls is the common choice because it cools the room on its own schedule and leaves the main system alone.
What glass should a Houston sunroom have?
Insulated low-E glass with a low solar heat gain coefficient, which is the number that tells you how much of the sun’s heat gets through. We put the best glass on the west and south walls, where the afternoon sun hits hardest, and talk about overhangs before adding more glass.
Will my HOA allow a sunroom?
Many do, with rules about the roofline, materials and how close you can build to the property line. We put together the drawings and product sheets your HOA asks for and hold the start date until approval is in your hands.
How long does it take to build one?
Design, permit and HOA approval often take longer than the build itself. Once construction starts, the timeline depends on size, foundation type and weather. You get the schedule in writing before the first form board goes down.
